It happens that most of the damage is located on the fuselage and very little in the area around motors, and the military is expecting to add armor to the fuselage, where the density of hits is highest.
Then, Where are bullet holes not?
The armor, said Wald, doesn’t go where the bullet holes are. It goes where the bullet holes aren’t: on the engines. Wald’s insight was simply to ask: where are the missing holes? The ones that would have been all over the engine casing, if the damage had been spread equally all over the plane?

Abraham Wald (/wɔːld/; Hungarian: Wald Ábrahám, Yiddish: אברהם וואַלד;31 October 1902 –13 December 1950) was a Hungarian/Hungarian Jewish mathematician who contributed to decision theory, geometry, and econometrics, and founded the field of statistical sequential analysis.
Where should planes be reinforced?
After analyzing where its planes had suffered the most damage, it determined that it needed to reinforce the planes‘ wingtips, central body and elevators. But a statistician named Abraham Wald argued otherwise. He thought the Navy should reinforce the armor of the planes‘ nose, engines and mid-body.
What is the bullet hole misconception?
Wald explained that if a plane made it back safely with, say, bullet holes in the fuselage, it meant those bullet holes weren’t very dangerous. Armor was needed on the sections that, on average, had few bullet holes such as the cockpit or the engines. Planes with bullet holes in those parts never made it back.

Why is there a hole in aircraft windows?
According to Mark Vanhoenacker, a British Airways pilot who writes for Slate, the innermost pane is mostly to protect the second and third panes, which are “designed to contain this difference in pressure between the cabin and the sky.” The bleed hole, then, allows pressure to be balanced out between the cabin and gap …
What happens if a plane gets a hole?
Seeing as you’re so high up, a hole in the plane can lead to violent decompression and a loss of atmosphere, so the flight crew needs to get more atmosphere into the plane and equalize the pressure. The way to do that would be to drop to the much safer altitude of 10,000 feet, where the atmosphere isn’t as thin.
